Solution

When magnesium is burnt in air, magnesium oxide and magnesium nitride are obtained.
$2 M g + a i r (O_{2}, N_{2}) h e a t - - \to M g O + M g_{3} N_{2}$
On hydrolysis, magnesium oxide forms magnesium hydroxide.
$M g O + H_{2} O \to M g (O H)_{2}$
On hydrolysis, magnesium nitride forms ammonia.
$M g_{3} N_{2} + 6 H_{2} O \to 3 M g (O H)_{2} + 2 N H_{3}$
